Even after reading a lot of material on the subject I'm still not really clear
on how to assign excitations and ports in hfss. I'd like to clear up my confusion by trying an "elementary" example : I'd like to calculate the
capacitance of a a parallel plate capacitor : two rectangular or circular
plates separated by distance d and with some material in the middle. The
geometry and material definition is straight forward and I have no trouble with that. I think I know how to setup an "airbox" around the system and
radiation boundaries... The main question is this : how do you define the
"ports" here?...I'd imagine this as a 2-port system which I can get S-parameters for; I can get capacitance from S-params which I can compare
against equations...
